Abstract: A rotatory vibrating system is used in surveys of the acoustic properties of theshallow earth. The vibrator itself is of eccentric-mass (or "swinging-weight") form. Coupled to a flywheel, it decelerates freely from a selected high frequency to a selected low frequency. The observed deceleration rate is manipulated to give a measure of the said acoustic properties. The eccentricity of the vibrator is then annulled, and the flywheel and vibrator accelerated back to the selected high frequency for another measurement at another location. Display means are provided to facilitate visual interpretation of the results.

Abstract: A system and method for assigning the vertices of an envelope to one or more elements of a skeleton in an animation model. Bounding volumes are defined for skeleton elements and define effective volumes which are positioned relative to the skeleton elements to encompass one or more vertices of envelopes. The bounding volume geometry may be defined as desired and a desired assignment operation type is selected for the bounding volume. When automated assignment is performed, assignment of the vertices within the bounding volumes is performed in accordance with the selected assignment operation for each bounding volume and with a selected maximum number of elements to which each vertex may be assigned. Bounding volumes may be overlapped to provide versatile automated assignment and the bounding volumes and corresponding assignment operations are stored with the skeleton and therefore are independent of the envelopes employed. Thus, the bounding volumes and assignment operations can be used both for the assignment of pre-production quality, low resolution, envelopes and for the subsequent assignment of production quality, high resolution, envelopes, as desired.

Abstract: Grain growth inhibitors including vanadium carbide, chromium carbide, tantalum carbide, and niobium carbide are incorporated into a cobalt/tungsten carbide matrix during the formation of the cobalt/tungsten carbide matrix. A precursor powder is formed by combining in solution a cobalt composition, a tungsten composition and a grain growth inhibiting metal composition, which is then spray dried.  The precursor compound is then carburized in carbon monoxide and carbon dioxide to form cobalt/tungsten carbide matrix. This is then further carburized in a hydrocarbon hydrogen gas at an elevated temperature to cause the grain growth inhibiting metal present to form the carbide. The second carburizing step is conducted with a carburizing gas having a carbon activity greater than about 2 for a relatively short period of time at 900° C to 10000° C.

Granted: 2000-10-24
Abstract: A method and system in which calls made on two or more phone lines of a customer are aggregated for billing and discount billing plans to which the customer subscribes are applied to the aggregated phone usage of the customer. In order to price a call made over a network by a customer of the network, information specifying a billing plan of the customer and information specifying a plurality of telephone lines to which the billing plan applies are stored. A call made from one of the plurality of telephone lines is received at a network switch and record that describes the call is generated. The record is received at a billing analysis system and a priced call value for the call is determined based on the record and the information specifying the customer billing plan. The record that describes the call comprises an identifier of the telephone line from which the call was made and priced call value for the call is determined by accessing the information specifying the customer billing plan using the identifier in the received record.

Title: Method and device for regenerating tin-plating solutions
Inventor: LIEBER HANS-WILHELM
IPC: C25D21/22
Filed: 1998-04-30
Granted: 2004-01-20
Abstract: The invention relates to a method and a device for regenerating exhausted tin-plating solutions which contain tin and copper ions, free complexing agent and complexing agent bound to the copper ions, as well as expended and unexpended reducing agent.  By means of a suitable rinsing technique, the rinse water of the tin-plating process is concentrated to a 10 to 15 percent dilution of the process solution. The regenerating solution thus produced is fed to an electrolytic cell. The electrolytic cell comprises a cathode chamber, a middle chamber and an anode chamber. The cathode chamber is separated from the middle chamber by an anion-exchange membrane and the anode chamber is separated from the middle chamber by a cation-exchange membrane. The regenerating solution is initially provided in the cathode chamber. Here, the interfering copper component is cathodically deposited.  After an appropriate residence time, the regenerating solution, depleted of copper, is transferred by pumping into the middle chamber where tin enrichment is effected by tin ions diffused from the anode chamber through the cation-exchange membrane. The regenerated solution is subsequently fed back into the tin-plating process.

Filed: 1997-05-16
Granted: 2006-08-01
Abstract: When using asynchronous transfer mode (ATM) in low bit rate applications, such as cellular voice communication, bandwidth utilization is significantly improved by employing decoupling minicells.  Decoupling minicells are of predetermined length, such as one octet, and are inserted into the payload of ATM cells when there is a delay in the availability of assigned minicells. As soon as an assigned minicell, which contains actual user data, becomes available, the assigned minicell can be inserted into the payload of the current ATM cell immediately after the last decoupling minicell. Unlike prior methods, there is no need to wait until the next ATM cell to insert an assigned minicell.

IPC: H04M7/00
Filed: 1997-04-25
Granted: 2005-10-25
Abstract: Billing identification numbers supplied to law enforcement agencies for monitored cellular calls are used to retrieve toll tickets generated by the cellular network (10). By processing the toll tickets, an identification is made by the agency of the A-party (24) to and routing of the monitored cellular call. Calling line identification (CLI) information is supplied to the monitoring law enforcement agency for each monitored call. The CLI information identifies the directory number of the A-party to the monitored cellular call when the A-party (24) comprises another cellular subscriber (14(1)). When the A-party comprises a wireline subscriber in a public switched telephone network (PSTN) (26), the CLI information delivered to the monitoring law enforcement agency comprises either the calling line identification (CLI) information obtained over an integrated services user part (ISUP) trunk connection (identifying the wireline A-party) (56), or converted A-number identification (ANI) information obtained over a non-ISUP trunk connection (identifying routing and switching information) (56).

Title: Transmission system for transmitting a flexible multiplex signal
Inventor: VAN DEN HEUVEL SEBASTIAAN ADRI
IPC: H04N7/24
Filed: 1998-02-16
Granted: 2006-04-11
Abstract: In an MPEG-2 transmission system, a plurality of programs each consisting of a plurality of elementary streams are multiplexed on a transport stream by a multiplexer (8). The transport stream is transmitted by the transmitting means (10) via a transmission medium (16) to a receiver (18). In the receiver (18) the signal is demodulated by the receiving means ( 12) and demultiplexed by the demultiplexer (14). In order to be able to find the different elementary streams which form a program, several tables are used. Said tables which can change over time are updated by information present in the transport stream. The tables are identified by a version number in order to be able to distinguish different versions of them. The version numbers are not necessarily subsequent numbers. In a prior art, transmission system filtering has to be performed on all possible version numbers to find updates of a table. In the transmission system according to the present invention, filtering is performed by only selecting sections having a version number which is different from the previous version numbers.
